Want to get back together with your ex-girlfriend

My world has lost its luster without you ~

This is not something that can be decided on the one hand.

Understand the reasons for failure ~ I like to pursue it with my heart ~

If you want to get it back, just work hard ~ first of all, you must know yourself and know yourself. Knowing that you are not good enough in that respect will make the other person unbearable. Find it and overcome it.
